Industrial Gases: Driver of the Global Economy Through 2035
Silicon chips, green hydrogen, battery cathodes, rocket propellant, MRI machines, MAP food packaging — none of these exist without industrial gases. The sector is not a commodity supplier. It is the invisible infrastructure of every high-technology industry on Earth, and it is growing faster than global GDP.
Market scale and forecasts
The global industrial gases market was valued at approximately $105 billion in 2023. By 2025, recovering supply chains and accelerating demand from the semiconductor industry and clean energy sector pushed this to $113–119 billion. Fundamental forecasts through 2035 point to an unprecedented influx of capital.

| Business Research Co. | $110.9B | $156.0B (2030) | 7.1% | Hydrogen economy, semiconductors |
The Asia-Pacific region holds approximately 36–37% of global consumption, driven by industrialisation in China, India and South Korea. Europe accounts for up to 42% of global revenue due to high value-added products, while North America (~27%) remains a hub for ultra-pure gases serving aerospace, medicine and microchip manufacturing. In physical volume terms, production is expected to grow from 1.74 billion tonnes in 2025 to 2.16 billion tonnes by 2030.
The economic multiplier effect: why gases are not a commodity
To understand the true value of industrial gases, it is necessary to look beyond direct revenue and examine their role through the lens of inter-industry input-output analysis. A 2024 study of the EU-27 economy (EIGA) quantifies the sector’s systemic impact:
| Economic effect (EU-27, 2024) | Revenue (bn EUR) | Gross value added (bn EUR) | Employment |
|---|---|---|---|
| Direct effect | 21.2 | 7.9 | 40,100 |
| Indirect effect (supply chain) | 21.3 | 9.2 | 102,200 |
| Induced effect | 8.6 | 4.0 | 47,900 |
| Total integral effect | 51.2 | 21.0 | 190,200 |
The exceptionally high employment multiplier (4.7) is explained by the sector’s extreme capital and energy intensity — energy costs account for 44.2% of GVA versus an 8% industry average. This generates massive demand throughout the supply chains of energy carriers, cryogenic equipment, engineering and financial services. Every 100 direct jobs in gas production support an additional 370 jobs elsewhere in the economy.
Artificial intelligence and semiconductors: why Moore’s Law depends on ultra-pure gases
The explosive growth of generative AI, machine learning, data centres and autonomous vehicles creates unprecedented demand for computing power — and none of it is possible without specialised industrial gases. The industry’s transition to 5 nm, 3 nm and sub-3 nm process nodes has raised purity requirements to levels that would have been considered extraordinary a decade ago. While 99.99% gas purity (parts per million) was standard for previous chip generations, modern microelectronics require “six nines” (99.9999%) with impurities measured in parts per billion.
Training AI models requires High-Bandwidth Memory (HBM), produced by vertically stacking memory layers — a process demanding significantly more etching cycles and plasma chamber cleaning than traditional planar production, driving sharp growth in fluorine-containing gas consumption.
| Gas category | Specific gases | Role in AI chip and semiconductor production |
|---|---|---|
| Deposition gases | SiH₄, GeH₄, NH₃ | Precursors forming ultra-thin silicon, germanium and nitride dielectric films during Chemical Vapour Deposition (CVD) |
| Etching gases | SF₆, Cl₂, F₂, CF₄ | Deep Reactive Ion Etching (DRIE) forming complex three-dimensional nanoarchitecture of microchips |
| Cleaning gases | NF₃ | Critical for plasma CVD chamber cleaning. Demand growing over 8% annually due to 3D NAND and HBM multi-layer architecture |
| Inert / carrier gases | N₂, Ar, He | Nitrogen purges cleanrooms and prevents oxidation. Argon for plasma etching. Helium for thermal management in EUV lithography |
The environmental paradox: The gases essential for manufacturing energy-efficient AI chips have extreme global warming potential. NF₃ has a GWP of 17,000 times CO₂. C₂F₆ and other fully fluorinated compounds run even higher. This forces the industry to invest billions in abatement systems, raising semiconductor production costs by 10–15%. Managing the lifecycle of these gases is now a primary challenge for every major tech corporation operating fabs in the EU and US.
Gas producers are integrating directly into the semiconductor supply chain. Air Liquide is investing over $250 million to build a dedicated facility in Idaho supplying a major memory chip manufacturer with ultra-pure nitrogen, oxygen and argon, powered entirely by renewable energy. TSMC’s $165 billion Arizona fab complex similarly forms an entire ecosystem of on-site gas production around itself.
Energy transition and decarbonisation
Industrial gases are transitioning from consumables to primary infrastructure for decarbonisation. IEA data shows clean energy investments reaching $1.5 trillion in 2025 — double fossil fuel investments. Industrial gases sit at the centre of all three pillars of the energy transition.
Heavy industry and metallurgy
Traditional manufacturing still generates the majority of gas demand. In Europe: manufacturing 28.4%, chemical industry 20.8%, metallurgy 18.6% — approximately 70% combined.
The structural shift toward electric arc furnaces (EAF) is significant: EAF capacities grew 11% since 2020 with a further 24% growth expected by 2030. Direct Reduced Iron (DRI) technology — where natural gas or hydrogen replaces coal — now accounts for 42% of steelmaking capacities under construction. All these processes demand precise control of the gas environment. Argon purging in secondary metallurgy removes impurities from high-strength steel and special alloy melts without risk of chemical reactions. Shielding gas mixtures ensure weld seam integrity across automotive, shipbuilding and heavy fabrication.
Aerospace: gases at every stage
When NASA’s Space Launch System launched Artemis I, its main engines consumed hundreds of thousands of gallons of liquid oxygen and liquid hydrogen produced by Linde. The space propulsion market — valued at $10.2 billion in 2024 — is forecast to reach $20 billion by 2030 at a CAGR of 11.9%.
Additive manufacturing of rocket components (combustion chambers, nozzles, turbopumps) from metal powders like Inconel and titanium requires argon to prevent oxidation of molten metal under laser impact. Helium pressurises rocket fuel tanks and purges systems before launch — its chemical inertness and extremely low freezing point make it irreplaceable for this application. The growing pressure from climate regulators to transition from hydrocarbon fuels (RP-1, HTPB) to cleaner methane and hydrogen will require a new wave of cryogenic infrastructure development.
Healthcare, food and food security
Healthcare accounts for approximately 27% of global industrial gases market revenue — the largest single end-use segment. Medical gases are not auxiliary substances; they are registered pharmaceutical products subject to pharmacopoeial standards. The COVID-19 pandemic demonstrated the absolute criticality of medical oxygen infrastructure: European gas company networks prevented systemic collapse, while shortages in South Asia and Africa caused avoidable deaths.
The food sector consumes approximately 8.7% of technical gases. Modified Atmosphere Packaging (MAP) using precision N₂/CO₂ mixtures extends perishable product shelf life several times over without chemical preservatives, directly reducing food waste. Liquid nitrogen enables ultra-fast cryogenic freezing that preserves cellular structure and moisture. Nitrogen is also a critical feedstock for ammonia synthesis — the basis of nitrogen fertilisers that underpin global food security.
Helium: the critical resource of the 21st century
Unlike nitrogen or oxygen, helium is not replenished in the atmosphere on an industrial scale. It is extracted exclusively as a by-product during natural gas field development. Its properties — chemical inertness, highest thermal conductivity of any gas, lowest boiling point of any substance at −268.9°C — make it irreplaceable across multiple critical applications:
- Quantum computing — superconducting qubits require cooling to near absolute zero; liquid helium is the only substance capable of this temperature regime
- EUV lithography — optical systems in ASML’s $400M machines require inert atmosphere for ultra-precise mirror protection
- MRI machines — superconducting magnets cooled by liquid helium produce the magnetic fields necessary for medical imaging
- Fibre optics — cooling glass preforms during optical fibre drawing that forms the global internet
- Aerospace — system purging, infrared sensor cooling, instrument operation
Global helium demand is expected to double by 2035. The EU and Canada have officially designated helium a “critical mineral.” The main suppliers are the US, Qatar, Algeria and Russia — a geopolitically concentrated supply chain with documented shortage cycles (Helium Shortage 4.0). Export-import operations in rare gases generate value 2.5 times greater than their local EU production volume, making this the highest-margin segment in the global gas economy.
Neon, krypton and xenon face a similar situation. These gases, vital for excimer lasers in semiconductor lithography, are produced as by-products of air separation. Their supply is structurally limited and has been repeatedly disrupted by geopolitical events — most severely in 2022 when Ukraine-based neon production, which supplied approximately 50% of global semiconductor-grade neon, was disrupted. This episode triggered a global redesign of specialty gas supply chains.
EU climate regulation: CBAM, EU ETS and market distortions
The EU Emissions Trading System (EU ETS) and the Carbon Border Adjustment Mechanism (CBAM) are reshaping the economics of gas production. Because base gas production is energy-intensive (44.2% of GVA), the cost of electricity and CO₂ quotas directly dictates profitability. With CBAM rollout, free allocations within Europe will be phased out from 2026 to 2034, with the CBAM factor declining from 0.975 to zero.
An EIGA report identifies a structural asymmetry between insourcing and outsourcing models that threatens market efficiency. If an oil refinery produces hydrogen itself (insourcing), it is regulated under the refinery benchmark and retains full free allocation. If the same hydrogen is produced by an independent gas company on the same premises (outsourcing), it falls under the hydrogen benchmark with aggressive quota reduction. Modelling shows financial losses (NPV) for gas companies of €1.3–1.7 billion by 2034, artificially rendering efficient outsourcing unprofitable.
A parallel distortion exists in electricity subsidies. A copper smelter in Germany operating its own air separation unit received €11.8 per tonne of oxygen produced (46% of electricity cost) in 2024. An independent gas supplier operating an identical ASU received nothing. Establishing technological neutrality between insourcing and outsourcing is a prerequisite for the gas industry to adequately finance the green transition.
Strategic implications for industrial enterprises
For industrial plant executives, procurement professionals and investors, the 2025–2035 landscape generates three strategic imperatives:
- Supply integration as a factor of survival — securing long-term, fail-safe supply chains for industrial gases (particularly helium and specialty gases) must be elevated from operational routine to the highest strategic priority. Geopolitical concentration of noble gas supply is a documented risk, not a theoretical one.
- Decarbonisation capital allocation — transitioning air separation units to renewable energy sources, deploying CCUS systems, and developing rare gas reclamation methods are investments in competitive positioning on global markets under CBAM, not optional green initiatives.
- Regulatory engagement — the CBAM/EU ETS asymmetry between insourcing and outsourcing requires active industry engagement with regulators to establish a level playing field. Companies that understand this regulatory landscape are already factoring it into long-term procurement and infrastructure decisions.
The core strategic truth: Whoever controls reliable supply of nitrogen, oxygen, argon, hydrogen and helium controls the operating conditions of every advanced manufacturing facility, every hospital, every semiconductor fab and every clean energy installation. Industrial gases are not a cost line — they are a strategic asset class. The period 2025–2035 will separate organisations that treat gas supply as a commodity from those that treat it as critical infrastructure.
